Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

long-video-to-shorts scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Long Video to Shorts

Use this workflow when one long source video carries the output. Supporting clips may exist, but the short-form story comes from selecting self-contained moments inside the long source.

This is a OpenChatCut-native workflow. Use the current project, assets, transcript, timeline, and OpenChatCut editing tools. Do not depend on external download, transcription, ffmpeg, or auto-crop pipelines unless the user explicitly asks for an external source that is not already in the project.

Workflow

  1. Read the project state before editing. Identify the primary long video, duration, language, speakers, current timeline, transcript readiness, visual descriptions, and aspect ratio.
  2. Confirm that one long source carries the output. If the project is mainly multiple raw clips with no dominant long source, switch to the Multi Clips to Reels workflow.
  3. Determine only missing constraints that would change the edit: platform, clip count, target duration, audience, style, captions/title text, music, and whether the user wants options or direct creation.
  4. If more than one missing constraint remains, ask for them in one <widget> after loading widget-forms. Use text fields for open-ended fields like topic, spoken language, audience, or goals; use single/multi choice fields for bounded choices like platform, count, duration, captions, or music.
  5. Use transcript ranges when available. If transcription is unavailable or unreliable, inspect visual/audio content and ask only for missing context that changes selection.
  6. Scan for moments that can stand alone: clear setup, hook, claim, proof, emotional turn, lesson, conflict, demonstration, or payoff. Read references/short-form-selection.md when scoring or comparing candidates.
  7. Build a compact candidate plan before heavy editing. For each output include source range, opening hook, why it stands alone, payoff, target duration, platform treatment, and risks.
  8. If the user gave enough constraints and asked to create directly, proceed after stating the plan. If the source is very long, the request is vague, or the requested count is high, create or preview the first strongest clip before batching the rest.
  9. Cut on clean word, phrase, action, or beat boundaries. Tighten filler, false starts, repeated attempts, and dead time only when meaning and tone stay intact.
  10. Package for the target platform: aspect ratio/crop, title text, styled captions, music, light motion graphics, zooms, speed changes, or transitions only when they support the selected moment.
  11. QA before reporting done: hook in first seconds, clear payoff, standalone clarity, no misleading title, clean boundaries, platform fit, requested count/duration, timeline names, and export readiness.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
